DE2749247C3 - Miter connection for door frame cladding - Google Patents

Description

Receipt of the legs 10 and 11 is provided.

The function of the illustrated miter connection is as follows:

The bracket 3 can be seen in FIG Way from the rear to the parts 1 and 2 to be connected, with the tavern! 10 and 11 partially engage in the blind bores 16 and 17, respectively. If the bracket 3 is in the position shown in FIG. 3 pressed in, the garments 1 and 2 tilt under the action of the legs 10 and 11 exercised train (arrows 18, 19) in the manner shown in Fig. 3, so that first of all on the viewing surface 20 of the decorative clothing a gap 21 appears.

Then the wood screws 14 and 15 are inserted through the holes 12 and 13 in the clothing parts 1 and 2 screwed in. In doing so, sicii deforms the bracket 3 in the manner shown in FIG roof-shaped web sections 6 and 7 are weakened in the outer area). This will make the garments 1 and 2 now pulled tightly together in the area of the visible surface 20, so that the gap 21 is verschu indet At the same time, the clothing parts 1 and 2 are aligned in terms of area against each other, so that a flush course of the visible surface 20 in the area of the miter joint 4 results.

The force acting on the clothing parts 1 and 2 when the wood screws 14 and 15 are screwed in is with the arrows 22,23 indicated schematically.

It can thus be seen that the clamp 3 designed according to the invention has a double function, by on the one hand pressing the two pieces of clothing 1 and 2 against each other in the area of the miter joint 4 and on the other hand, aligns them in terms of area.

On the inside of the clamp 3 coming to rest on the clothing parts 1 and 2, a Adhesive coating (in addition to or instead of using wood screws 14, 15) is provided will. When the clamp 3 is pressed against the lining parts 1 and 2, a good result is obtained in this way Surface connection between the clamp 3 and the clothing parts 1 and 2.

Claims (3)

Patent claims: 1. Miter connection for door frame cladding, with a clip arranged on the back of the cladding parts to be connected, which has legs coming into engagement in blind bores of the two cladding parts on different sides of its web lying above the miter joint, which in the installed state with contact surfaces on the adjacent walls of the two blind bores are pressed on, characterized in that the plate-shaped web of the clamp (3) consists of sheet steel and is angled around its center line (5) in the shape of a roof that the blind bores (16, 17) of the two pieces of clothing (1, 2 ) engaging legs (10,11) with the connecting web sections (6, 7) of the brackets (3) form an angle (β) greater than 90 ° and with each other an angle less than 90 ° and that to connect the web sections (6, 7 ) with the associated clothing items (1, 2) through through holes (12, 13) in the web sections (6, 7) gripping wood screws (14, 15) and / or an adhesive coating arranged on the inside of the clamp (3) are or is provided. 2. Miter connection according to claim!, Characterized characterized in that the angle (λ) of the bracket (3) in the region of its center line (5) between 160 and 178 °, preferably between 165 and 175 °, and the angle (/?) Between the legs (10, 11) and the adjoining web sections (6, 7) of the clamp (3) between 92 and 110 °, preferably between 95 and 105 °. 3. Miter connection according to claim 1 or 2, characterized in that the two legs (10, 11) on the outer edges (8, 9) of the on opposite sides of the center line (5) plate-shaped web of the clamp (3) is provided and semicylindrical, the convex Curved ■ contact surfaces of the two legs (10, 11) point towards one another. The invention relates to a miter connection for door frame cladding, with one on the back ropes of the to be connected to each other to be connected pieces of clothing arranged brackets on different sides of your The web located above the miter joint / to encroach on the blind holes of the two pieces of clothing coming Has legs that in the installed / ustand with contact surfaces on the adjacent walls of the both blind holes are pressed. In a known miter connection of this type (see. The German Offenlegungsschrift 21 27 432) is the Clamp designed as a spring, the inwardly directed spring legs each having a bend have, which rest on the bottom of the associated blind hole. The blind holes must be such a spring element are relatively close together, so that there is a risk that the up to Miter joint remaining wall is stressed too much and is bent. Arched on both sides However, wall parts mean that the ends of the clothing parts to be connected are not close to one another lie. A gap can also occur if the spring force over time The assembly is associated with additional costs, as a special tool, namely a Spreader pliers, is required. Finally, the manufacture of the clip from spring steel also causes relative high costs. The invention is therefore based on the object a miter connection of the type specified at the beginning, avoiding the deficiencies explained develop that can be manufactured at extremely low cost and that is easy to assemble exact contraction of the two lining parts with simultaneous surface stabilization. This object is achieved according to the invention in that the plate-shaped web of the clip consists of sheet steel and is angled roof-shaped around its center line that the blind holes of the two pieces of clothing engaging legs with the connecting web sections of the clamps enclose an angle greater than 90 ° and with each other an angle less than 90 ° and that for Connection of the web sections with the associated clothing parts through through holes in the Wood screws engaging web sections and / or one arranged on the inside of the bracket Adhesive coating are provided or is. This has the advantage that the individual Garments can be permanently connected with simple means. Further advantageous refinements of the invention are the subject of the subclaims. more details are explained in more detail in the description of an exemplary embodiment illustrated in the drawing. It shows Fig. 1 is a plan view of the back of a miter joint according to the invention of the decorative clothing a door frame and Fig. 2 to 4 sections ment of the line H-II of Fig. 1 in three different stages during the assembly of the bracket. To connect the garments 1 and 2 of the decorative cladding of a door frame is a plate-shaped Bracket 3 is provided, which - like in particular the Fig. 2 to 4 can be seen - around its center line 5 lying above the miter joint 4, slightly roof-shaped is angled. The two web sections 6 and 7 of the clamp 3, which are inclined towards one another in a roof-shaped manner form an angle <x of 160 to 178 ", preferably between 165", with one another in the region of the center line 5 and 175 '.a. On the opposite sides of the center line 5 Located outer edges 8 and 9 of the clamp 3 are semi-cylindrical legs 10 and II provided whose convex curved surfaces point towards one another. These legs 10 and 11 close with the structural sections 6 and 7 that support them the bracket 3 forms an angle which is between 92 and 110 ", preferably between 95 and 105". the the two legs 10 and 11 together form a (in in the drawing) that is significantly smaller than 90 ", for example between 20 and 40 ". The bracket 3 made of sheet steel also contains 5 each on different sides of its center line a through hole 12 or 13 for receiving a wood screw 14 or 15. In the two parts of the lining that are to be connected to one another I and 2 is a blind hole 16 and 17, respectively
